The diet of the Atlantic cod consists of fish such as herring, capelin, and sand eels, as well as mollusks, crustaceans and sea worms. Stomach sampling studies have discovered that small Atlantic cod feed primarily on crustaceans, while large Atlantic cod feed primarily on fish. In certain regions, the main food source is decapods with fish as a complementary food item in the diet. Wild Atlantic cod throughout the North Sea depend, to a large extent, on commercial fish species also used in fisheries, such as Atlantic mackerel, haddock, whiting, Atlantic herring, European plaice, and common sole, making fishery manipulation of cod significantly easier.

In our modern society almost all fish, including Atlantic Cod, are now produced through aquaculture. Aquaculture is defined as "the rearing (raising) of aquatic animals or the cultivation of aquatic plants for food". The raising of Atlantic Cod starts with the selection of the best female stock breed. These fish are selected from previously grown market fish, located in off shore sea cages.

Aquaculture (fish farming) is used for all Atlantic Cod production, so that the environment and natural (wild) fish species are essentially unaffected. Fish are sold without further processing, so little to none of the animal is wasted. The only environmental concern from Atlantic Cod is excess nutrients produced in their feces. If left un-filtered in natural environments, these feces could lead to denitrification.

Young Atlantic cod avoid larger cod and pouting (Trisopterus luscus) and crabs on a wreck in the southern North Sea Atlantic cod are apex predators in the Baltic and adults are generally free from the concerns of predation. Juvenile cod, however, may serve as prey for adult cod, which sometimes practice cannibalism. Juvenile cod make substrate decisions based on risk of predation. Substrates refer to different feeding and swimming environments.

Shoaling Atlantic cod on a wreck in the North Sea Atlantic cod are a shoaling species and move in large, size-structured aggregations. Larger fish act as scouts and lead the shoal's direction, particularly during post spawning migrations inshore for feeding. Cod actively feed during migration and changes in shoal structure occur when food is encountered. Shoals are generally thought to be relatively leaderless, with all fish having equal status and an equal distribution of resources and benefits.

Atlantic cod act as intermediate, paratenic, or definitive hosts to a large number of parasite species: 107 taxa listed by Hemmingsen and MacKenzie (2001) and seven new records by Perdiguero- Alonso et al. (2008). The predominant groups of cod parasites in the northeast Atlantic were trematodes (19 species) and nematodes (13 species), including larval anisakids, which comprised 58.2% of the total number of individuals. Parasites of Atlantic cod include copepods, digeneans, monogeneans, acanthocephalans, cestodes, nematodes, myxozoans, and protozoans.

In the summer of 1929 he participated in studies of Atlantic cod and White Sea herring as an assistant at the Department of Experimental Ichthyology. These activities resulted in him writing three papers (on causes of albinism in birds (1927), morphology of the stingray brain (1928) and systematisation of Atlantic cod (1931)), two of which were published whilst Taliev was still studying at University. In the beginning of 1932, Taliev began working at the Baikal Limnological Research Station as a senior researcher.

Species that are over-fished, such as the variants of Atlantic cod, are more susceptible to the effects of climate change. Over- fished populations have less size, genetic diversity, and age than other populations of fish. This makes them more susceptible to environment related stress, including those resulting from climate change. In the case of Atlantic cod located in the Baltic Sea, which are stressed close to their upper limits, this could lead to consequences related to the population's average size and growth.

Preserved codfish Cod is popular as a food with a mild flavor and a dense, flaky white flesh. Cod livers are processed to make cod liver oil, an important source of vitamin A, vitamin D, vitamin E and omega-3 fatty acids (EPA and DHA). Young Atlantic cod or haddock prepared in strips for cooking is called scrod. In the United Kingdom, Atlantic cod is one of the most common ingredients in fish and chips, along with haddock and plaice.

Capture of Atlantic Cod 1950-2005 (FAO) Human activities have affected stocks of many species of teleost, through overfishing, pollution and global warming. Among many recorded instances, overfishing caused the complete collapse of the Atlantic cod population off Newfoundland in 1992, leading to Canada's indefinite closure of the fishery. Pollution, especially in rivers and along coasts, has harmed teleosts as sewage, pesticides and herbicides have entered the water. Many pollutants, such as heavy metals, organochlorines, and carbamates interfere with teleost reproduction, often by disrupting their endocrine systems.

Canadian Atlantic Cod (Gadus morhua), are cold water fish, which weigh 2 to 3 kg in the wild. Atlantic Cod were originally found in the Atlantic Ocean, along the borders of both Canada and England and all the way down to the southern United States. Heavy fishing in these areas, in the late 1800s and early 1900s led to a massive decline in Cod population. Today, they are grown in onshore temperature controlled, seawater tanks as eggs and eventually taken to sea cages when more developed.

Cod fish are actually carnivorous animals and will even eat each other if prevalent size ratios are available. However aquatic farms have recently been trying to turn Atlantic Cod's carnivorous diet to a more herbivorous one; as already done in chickens This would drastically lower the already low price of feed for future generations. ;Nutritional information Once market size is reached, Atlantic Cod fish offer a bounty of nutrients including a surplus amount of complete proteins, omega-3 fatty acids, iron and B vitamins. A serving or 98g of Atlantic Cod offers us 40% of our daily protein intake, while at the same time containing low sodium levels Atlantic Cod when compared to other meat have a much lower level of saturated fat, while still holding a high protein level. In comparison, 98g of chicken provides about 18g of protein (under 40%).

3 November 2008 Free Site Search Engine The fishery has only recently begun to recover, and may never fully recover because of a possibly stable change in the food chain. Atlantic cod was a top-tier predator, along with haddock, flounder and hake, feeding upon smaller prey, such as herring, capelin, shrimp, and snow crab. With the large predatory fish removed, their prey have had population explosions and have become the top predators, affecting the survival rates of cod eggs and fry. Atlantic cod are demersal fish—they prefer sea bottoms with coarse sediments.
|

As mentioned earlier in the egg stage of development, Cod are fed yolk, followed by planktonic animals (ground plankton) in the larvae stage, and finally a pellet feed after leaving the onshore facility. The pellets fed to Atlantic Cod are mostly grain based, which are made of fish oil, bone meal, vitamins and minerals. Atlantic Cod have a 1 kg of feed to 1 kg of weight gain ratio. In some open water environments, this ratio is even more efficient, because Cod will eat other small natural organisms in the water.

White fish (Atlantic cod) White fish fillet (halibut – on top) contrasted with an oily fish fillet (salmon – at bottom) Whitefish or white fish is a fisheries term for several species of demersal fish with fins, particularly Atlantic cod (Gadus morhua), whiting (Merluccius bilinearis), haddock (Melanogrammus aeglefinus), hake (Urophycis), pollock (Pollachius), and others. Whitefish (Coregonidae) is also the name of several species of Atlantic freshwater fish. Whitefish live on or near the seafloor, and can be contrasted with the oily or pelagic fish which live in the water column away from the seafloor. Whitefish do not have much oil in their tissue, and have flakier white or light-coloured flesh.

In the North Atlantic, they primarily eat small schooling fish, demersal fish, and krill. A 2007 study showed that off Spitsbergen they fed almost exclusively on members of the euphausiid genus Thysanoessa (mainly T. inermis), but nearly a fifth also fed on small amounts of capelin. A small percentage of individuals, by decreasing frequency, also fed on polar cod, Atlantic cod, haddock, and copepods. Capelin dominated off Bear Island and in the southern Barents Sea, accounting for about three-quarters of their diet in both regions. Nearly half (nearly 46 per cent) also consumed euphausiids (Thysanoessa spp.) in the former area – haddock (12.5%), blue whiting (8.3%), polar cod, Atlantic cod, Atlantic herring, and copepods constituted the rest.

Northern gannets also forage for fish while swimming with their head under water. They eat mainly fish in length that shoal near the surface. Virtually any small fish (roughly 80–90% of their diet) or other small pelagic species (largely squid) will be taken opportunistically. Sardines, anchovies, haddock, smelt, Atlantic cod and other shoal-forming species are also eaten.

The capacity to catch fish became limitless. In addition, sonar technology gave an edge to detecting and catching fish. Sonar was originally developed during World War II to locate enemy submarines, but was later applied to locating schools of fish. These new technologies, as well as bottom trawlers that destroyed entire ecosystems, contributed to the collapse of Atlantic cod.

As a result, the overall billfish catch remained fairly stable. At Georges Bank, a decline in cod during the 1960s was accompanied by a rise in flatfish, and more recently, with the collapse of the predatory Atlantic cod, lobster catches in Maine have boomed.Duffy, J.

Ultimately, food selection by cod is affected by the food item size relative to their own size. However, providing for size, cod do exhibit food preference and are not simply driven by availability. Atlantic cod practice some cannibalism. In the southern North Sea, 1–2% (by weight) of stomach contents for cod larger than consisted of juvenile cod.

With the reopening of the limited cod fisheries in 2006, nearly of cod were hauled in. In 2007, offshore cod stocks were estimated at 1% of what they were in 1977. Technologies that contributed to the collapse of Atlantic cod include engine-powered vessels and frozen food compartments aboard ships. Engine-powered vessels had larger nets, greater range, and better navigation.

The archipelago of Southwest Finland has been populated since the neolithic (roughly 2000-1300 BCE). The rich natural resources attracted people to the post-glacial archipelago in the Stone Age and Bronze Age. The Baltic Sea was much more saline in those days, thus offering large catches of Atlantic cod among other fish. A large population of grey seal inhabited the area.

As the cod grow, they feed on krill and other small crustaceans and fish. Adult cod primarily feed on fish such as capelin and herring. The northeast Arctic cod also shows cannibalistic behaviour. In 2012 the biomass of the Northeast Atlantic cod stock was estimated to be at an all-time high since scientists started observing stock status some 100 years ago.

Lateral line on an Atlantic cod Fish and some aquatic amphibians detect hydrodynamic stimuli via a lateral line. This system consists of an array of sensors called neuromasts along the length of the fish's body. Neuromasts can be free-standing (superficial neuromasts) or within fluid-filled canals (canal neuromasts). The sensory cells within neuromasts are polarized hair cells contained within a gelatinous cupula.

Atlantic cod have been recorded to swim at speeds of a minimum of and a maximum of with a mean swimming speed of . In one hour, cod have been recorded to cover a mean range of . Swimming speed was higher during the day than at night. This is reflected in the fact that cod more actively search for food during the day.

Swimming and physiological behaviours change in response to fluctuations in water temperature. Respirometry experiments show that heart rates of Atlantic cod change drastically with changes in temperature of only a few degrees. A rise in water temperature causes marked increases in cod swimming activity. Cod typically avoid new temperature conditions, and the temperatures can dictate where they are distributed in water.

The 2006 IUCN Red List names 1,173 fish species that are threatened with extinction. Included are species such as Atlantic cod, Devil's Hole pupfish, coelacanths, and great white sharks. Because fish live underwater they are more difficult to study than terrestrial animals and plants, and information about fish populations is often lacking. However, freshwater fish seem particularly threatened because they often live in relatively small water bodies.

Prior to the collapse of the Grand Banks (and other) stocks due to overfishing, salt cod was derived exclusively from Atlantic cod. Since then products sold as salt cod may be derived from other whitefish, such as pollock, haddock, blue whiting, ling and tusk. In South America, catfish of the genera Pseudoplatystoma are used to produce a salted, dried and frozen product typically sold around Lent.

Atlantic cod stocks were severely overexploited in the 1970s and 1980s, leading to their abrupt collapse in 1992. Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource. The term applies to natural resources such as: wild medicinal plants, grazing pastures, game animals, fish stocks, forests, and water aquifers.

Atlantic cod occupy varied habitat, favouring rough ground, especially inshore, and are demersal in depths between , on average, although not uncommonly to depths of . Off the Norwegian and New England coasts and on the Grand Banks of Newfoundland, cod congregate at certain seasons in water of depth. Cod are gregarious and form schools, although shoaling tends to be a feature of the spawning season.

Following an unofficial poll by the NRK P1 broadcaster in 1982, the hagfish was voted the national fish of Norway with over 4 000 votes, beating the second place (Atlantic Cod) by a large margin, as that fish only got 2,552 votes. However, the vote was most likely rigged and the result was overturned by the jury.Friis, R. (1982): «Slimåler» raser mot NRK/torsken, VG, s. 33, 15.

A classic example of stranded investments is the North Atlantic Cod Fishery - where the largest number of bottom trawling ships (e.g. those ships responsible for destroying the Cod spawning beds) were manufactured in the year that the fish stocks collapsed. The Global Association for Transition Engineering is registered charity number 1166048, registered with the UK Charity Commission on 14 March 2016. It is a "Charitable Incorporated Organisation" or CIO.

The Western Gulf of Maine Closure Area (WGoMAC) was established in 1998 in response to the decreasing Atlantic Cod (Gadus morhua) stock. WGoMAC is located off the shores of Massachusetts, New Hampshire, and Maine and is approximately . It is rectangular and runs in straight lines from 42° 15' to 43° 15' North, and 69° 55' to 70° 15' West. It is a year long closed area that prevents groundfish fishing.

Fish can be obligate or facultative shoalers. Obligate shoalers, such as tunas, herrings and anchovy, spend all of their time shoaling or schooling, and become agitated if separated from the group. Facultative shoalers, such as Atlantic cod, saiths and some carangids, shoal only some of the time, perhaps for reproductive purposes. Shoaling fish can shift into a disciplined and coordinated school, then shift back to an amorphous shoal within seconds.

Kleivan, "West Greenland," 608 Arctic char is fished off the east coast. The Greenland shark (Somniosus microcephalus) is rarely eaten because it is poisonous but can be edible after a complicated preparationPetersen 631 of either boiling the meat repeatedly or fermenting the meat. Global warming has shifted the migration of Atlantic cod, allowing for commercial fishing off Greenland's east coast. Drift ice can create problems during fishing season.

Freshwater fish species in Massachusetts include bass, carp, catfish, and trout, while saltwater species such as Atlantic cod, haddock, and American lobster populate offshore waters. Other marine species include Harbor seals, the endangered North Atlantic right whales, as well as humpback whales, fin whales, minke whales, and Atlantic white-sided dolphins. The European corn borer, a significant agricultural pest, was first found in North America near Boston, Massachusetts in 1917.

These analyses also suggest that T. finnmarchica is a near relative of the Atlantic cod, and that both Alaska and Norway pollock should be moved to genus Gadus. Norway pollock (Theragra finnmarchica) was listed as Near Threatened in the 2010 Norwegian Red List for Species based on criteria D1: "Very small or geographically very restricted population: Number of mature individuals". It is currently not listed in the IUCN Red List.

Amundsen supports oil exploration off the Lofoten archipelago, a major breeding ground for Atlantic cod. He also supports the involvement of Statoil, the Norwegian oil and gas company where the state of Norway is the majority shareholder, in exploitation of oil sands. Amundsen defines himself as climate sceptic. He has argued that climate problems are used to conduct socialist policies, saying that "for many socialists, CO2 has replaced Karl Marx".

The lateral line is clearly visible as a line of receptors running along the side of this Atlantic cod. The lateral line is a sense organ used to detect movement and vibration in the surrounding water. For example, fish can use their lateral line system to follow the vortices produced by fleeing prey. In most species, it consists of a line of receptors running along each side of the fish.

Their range covers the Arctic Ocean and Northwest Atlantic Ocean from Alaska to West Greenland, then south along the Canadian coast to the Gulf of St. Lawrence and Cape Breton Island generally from 45 to 75 degrees north. Their wholesome flesh is whitish and flaky but firmer and tougher and less desirable than that of the Atlantic cod. The stock of Greenland cod has been strongly reduced in recent years.

Smith Sound is one of the key breeding grounds for the Atlantic cod in Newfoundland and Labrador. High, sharp cliffs of slate dominate the coastline and dense forests of spruce and fir trees blanket the interior. Three communities fall within the municipality, Clifton, New Burnt Cove, and Burgoyne's Cove itself (listed west to east). The approximate population of Burgoyne's Cove is 100, but that varies because many people live there seasonally.

Additionally, juvenile Atlantic cod vary their behaviour according to the foraging behaviour of predators. In the vicinity of a passive predator, cod behaviour changes very little. The juveniles prefer finer-grained substrates and otherwise avoid the safer kelp, steering clear of the predator. In contrast, in the presence of an actively foraging predator, juveniles are highly avoidant and hide in cobble or in kelp if cobble is unavailable.

Herring and haddock were also taken in the southern Barents Sea (accounting for 41.5 and 28.7 per cent by frequency of occurrence, respectively), while sandeel (Ammodytes spp.), Atlantic cod, copepods, euphausiids, pollock, and blue whiting made up the rest of the diet. In the Norwegian Sea, herring was found in all individuals sampled (n= 10), with some (20 per cent each) also feeding on a small amount of capelin and blue whiting – an earlier study, based on data primarily obtained between 1943–1945, showed that they fed exclusively on herring off Vesterålen, while the diet off Lofoten was more varied, including herring (34 per cent by occurrence), pelagic crustaceans (23%), Atlantic cod (22%), haddock (6%), and a mixture of coalfish and flatfish for one individual (1.5%). In the North Sea, they primarily fed on sandeel (62%) and Atlantic mackerel (nearly 30%), with some feeding on herring (16.2%), small amounts of Mueller's pearlside (10.8%), copepods, haddock, capelin, and whiting.

Atlantic cod stocks were severely overexploited in the 1970s and 1980s, leading to their abrupt collapse in 1992. The tragedy of the commons is a type of replenishing resource management dilemma. The dilemma arises when members of a group share a common good. A common good is rivalrous and non-excludable, meaning that anyone can use the resource but there is a finite amount of the resource available and it is therefore prone to overexploitation.

Fish and chips is a hot dish consisting of battered fish, commonly Atlantic cod or haddock, and chips. It is a common take-away food. Western Sephardic Jews settling in England from the 16th century would have prepared fried fish like pescado frito, coated in flour and fried in oil. Chips appeared in the Victorian era; Dickens's 1859 A Tale of Two Cities mentions "husky chips of potatoes, fried with some reluctant drops of oil".

DANR09915 Fulltext: ProQuest Dissertations & ThesesMichael Harris, Lament for an Ocean: The Collapse of the Atlantic Cod Fishery, a True Crime Story. (1998) is a popular account. The fishing crisis of the 1990s saw the already precarious economic base of the many towns further eroded. The situation was made worse by both federal and provincial pursuit of programs of economic liberalization that sought to limit the role of the state in economic and social affairs.

One human burial was also found. Finds at the site include a wide variety of fish bones, most of which were Atlantic cod. This apparently distinguishes the site as primarily a fishing station; by comparison, a site on Moshier Island had a large number of faunal remains, principally deer. The site also includes a significant number of both stone tools and the debitage that results from their manufacture, suggesting extended seasonal occupation.

The tadpole cod (Guttigadus globosus) is a deepwater fish found in the oceanic islands off New Zealand and in the mid South Atlantic at depths ranging from 1200 to 1600 m. The tadpole cod is a member of the family Moridae, the morid cods, related to the true cods (of genus Gadus, family Gadidae). Like the familiar Atlantic cod, it has small whiskers (barbels) on its mouth. Specimens have been measured up to 18 cm.

However, in almost all commercial fish farms, feces are utilized (via vacuum) as liquid fertilizer, to be used for farm activities. Other beneficial environment factors are: factories are not required for further processing and feed source has minimal requirements from environment. Finally aquaculture developments need in-depth environmental review which includes Canadian Environmental Assessment Act (CEAA), to prevent harm from ocean habitats. Organic Atlantic Cod is also available as an alternative product.

Oceana claims that escolar has been mislabeled or otherwise confused with the following fish: Atlantic cod, oilfish (related to escolar but in a different genus), rudderfish, blue cod, black cod, king tuna, grouper, orange roughy, sea bass, gemfish, Chilean sea bass, albacore tuna, and white tuna. Oceana claims that this mislabeling, whether by ignorance or deceit, is more hazardous than the mislabeling of other fish due to the potential health effects of escolar.

In April 2019 Fisheries and Oceans Canada designated the Laurentian Channel Marine Protected Area (MPA). The main purpose of the Laurentian Channel Marine Protected Area is to protect the biodiversity of the region. This MPA explicitly protects porbeagle sharks, smooth sakes, basking sharks, black dogfishes, northern wolffish, and leatherback sea turtles, along with sea pens and other cold water coral. Atlantic cod is not officially protected, the Laurentian Channel MPA could encompass a possible spawning ground.

The Northwest Atlantic cod has been regarded as heavily overfished throughout its range, resulting in a crash in the fishery in the United States and Canada during the early 1990s. Newfoundland's northern cod fishery can be traced back to the 16th century. On average, about of cod were landed annually until the 1960s, when advances in technology enabled factory trawlers to take larger catches. By 1968, landings for the fish peaked at before a gradual decline set in.

The curled octopus is mainly found at depths between and may occur down to . It lives in the northeast Atlantic Ocean, including the English Channel, the North Sea, and the Mediterranean Sea. In recent years the North Sea populations have increased, probably due to overfishing of large predatory fish such as Atlantic cod. This has had a knock on effect on crab and lobster fisheries as the curled octopus readily enters pots to take the bait or the catch.

Canned cod liver Cod is popular as a food with a mild flavour and a dense, flaky white flesh. Young Atlantic cod or haddock prepared in strips for cooking is called scrod. Cod's soft liver can be canned or fermented into cod liver oil, providing an excellent source of vitamin A, vitamin D, vitamin E and omega-3 fatty acids (EPA and DHA). Cod flesh is moist and flaky when cooked and is white in colour.

The capelin or caplin (Mallotus villosus) is a small forage fish of the smelt family found in the North Atlantic, North Pacific, and Arctic oceans. In summer, it grazes on dense swarms of plankton at the edge of the ice shelf. Larger capelin also eat a great deal of krill and other crustaceans. Among others, whales, seals, Atlantic cod, Atlantic mackerel, squid, and seabirds prey on capelin, in particular during the spawning season while the capelin migrate south.

Fish show different responses to different noxious stimuli, even when these are apparently similar. This indicates the response is flexible and not simply a nociceptive reflex. Atlantic cod injected in the lip with acetic acid, capsaicin, or piercing the lip with a commercial fishing hook, showed different responses to these three types of noxious stimulation. Those cod treated with acetic acid and capsaicin displayed increased hovering close to the bottom of the tank and reduced use of shelter.

By the latter part of the 19th century, fishing was the main occupation, and continues to be important today, despite the fishing industry's woes in the last 15 years (including the devastating Atlantic cod moratorium). Today, tourism is an important industry. The Cape St. Mary's Ecological Reserve, just south of St. Bride's, draws thousands of visitors every year. Its rolling green hyper- oceanic barrens and meadows drop down dramatic sea-cliffs to the pounding surf below.

Germany, Denmark, and the Netherlands also have a trilateral agreement for the protection of the Wadden Sea, or mudflats, which run along the coasts of the three countries on the southern edge of the North Sea. At the end of the 19th century large quantities of herring were produced in Scotland. Today mainly mackerel, Atlantic cod, whiting, coalfish, European plaice, and sole are caught. In addition, common shrimp, lobster, and crab, along with a variety of shellfish are harvested.

In the United Kingdom, Atlantic cod is one of the most common kinds of fish to be found in fish and chips, along with haddock and plaice. It is also well known for being widely consumed in Portugal and the Basque Country, where it is considered a treasure of the nation's cuisine. Cod are highly prolific, producing several million eggs at each spawning. This contributes to their high population numbers, which, in turn, makes commercial fishing relatively easy.

Svolvær around 1890 The first town formation known in North Norway, Vågar, was situated around the narrow, natural harbor near Kabelvåg, just west of Svolvær. Vågar is mentioned in the book Heimskringla, and might have been established as early as the year 800 AD. Northern Atlantic Cod fisheries, particularly during winter months, have remained one of the most important economical foundations for the town. Other industries which have proved to be valuable resources for Vågan are fish farming (salmon), Secora and Lofotkraft.

In 1992 Prime Minister Brian Mulroney's Fisheries and Oceans Minister John Crosbie declared a moratorium on the northwestern Atlantic cod fishery, which had dominated the Newfoundland and Labrador economy for 500 years and provided sustenance for generations of residents. The moratorium was declared after cod biomass levels dropped to 1% of its historical level. The moratorium resulted in a loss of 35,000 jobs in 400 coastal communities in Newfoundland and Labrador, the largest one day job loss in Canadian history.

These conditions helped to create one of the richest fishing grounds in the world. Fish species include Atlantic cod, swordfish, haddock and capelin; shellfish include scallop and lobster. The area also supports large colonies of seabirds such as northern gannets, shear waters and sea ducks and various sea mammals such as seals, dolphins and whales. Overfishing in the late 20th century caused the collapse of several species, particularly cod, leading to the closure of the Canadian Grand Banks fishery in 1992.

The Pacific cod is an important commercial food species. It has three separate dorsal fins, and the catfish-like whiskers on its lower jaw. In appearance, it is similar to the Atlantic Cod. A bottom dweller, it is found mainly along the continental shelf and upper slopes with a range around the rim of the North Pacific Ocean, from the Yellow Sea to the Bering Strait, along the Aleutian Islands, and south to about Los Angeles, down to the depths of .

The common murre can venture far from its breeding grounds to forage; distances of and more are often observedLilliendahl et al. (2003) though if sufficient food is available closer by, birds only travel much shorter distances. The common murre mainly eats small schooling forage fish long or less, such as polar cod, capelin, sand lances, sprats, sandeels, Atlantic cod and Atlantic herring. Capelin and sand lances are favourite food, but what the main prey is at any one time depends much on what is available in quantity.

Cod fisheries are fisheries for cod. Cod is the common name for fish of the genus Gadus, belonging to the family Gadidae, and this article is confined to three species that belong to this genus: the Atlantic cod, the Pacific cod and the Greenland cod. Although there is a fourth species of the cod genus Gadus, Alaska pollock, it is commonly not called cod and therefore currently not covered here. Cod are demersal fish found in huge schools confined to temperate waters in the northern hemisphere.

The maximum recorded lifespan is 10 years for males and 14 for females, at which age they attain a length around 200 cm. Common ling is mainly a solitary and benthic species, which hides among rocks, crevices, and wrecks in deep water, although they are often free swimming in deep water. They are mainly piscivorous and their main prey include species such as Trisopterus esmarkii, Atlantic cod, Atlantic herring, and flatfish, but they also feed on crustaceans (e.g. European lobsters), cephalopods, and echinoderms (e.g. starfish).

Their growth rate is high, especially in their early life phases but slows as they attain sexual maturity. Their life cycle is thought to take just over a single year to complete, based on statolith analysis but the larger squid of over 500mm mantle length are thought to be 18 months to two years old. T.sagittatus juvenile The European flying squid preys on fish, crustaceans and cephalopods. In the more northerly part of its range small Atlantic herring (Clupea harenqus) are the main prey as are Atlantic cod (Gadus morhua).

Similarly, on Great Island in Newfoundland, 25% of the stomach contents were fish but 68% of regurgitants were fish. The most regularly reported fish eaten in Nova Scotia and Newfoundland were capelin (Mallotus villosus), Atlantic cod (Gadus morrhua), Atlantic tomcod (Microgadus tomcod), Atlantic mackerel (Scomber scombrus), Atlantic herring (Clupea harengus) and sand lance (Ammodytes hexapterus). Other prey often includes various squid, Jonah crabs (Cancer borealis), rock crabs (Cancer irroratus), sea urchins, green crabs (Carcinus maenas), starfish (Asterias forbesi and Asterias rubens) and other echinoderms, crustaceans and mollusks when they come across the opportunity.

They are opportunistic feeders which will prey on whichever suitable prey species are most abundant, Abstract it feeds mostly on small invertebrates, such as worms and crustaceans, for example in one study crustaceans were found to make up over 85% of the identifiable diet with the porcelain crab Pisidia longicornismaking up 43%. Molluscs, especially cockles, are also preyed upon by common dragonets. Common dragonets are an important prey item of Atlantic cod and pouting in the Irish Sea. Male common dragonets are territorial and they aggressively defend their territories from other males.

The jobs being created by this industry are also 90% located in rural, Aboriginal or small coastal cities. Just one example of this is in B.C, Kitasoo First Nation community, where aquaculture helped reduce unemployment to zero from 80 percent. Also an analysis by Indian and Northern Affairs determined that 61 First Nations could support salmon farms, 130 could develop trout farms and 123 would have access to clam, mussel and oyster farming. ;Constraints After the near extinction of natural Atlantic Cod in the wild, strict laws were made to prevent fishing of any sort.

Human trypsin has an optimal operating temperature of about 37 °C. In contrast, the Atlantic cod has several types of trypsins for the poikilotherm fish to survive at different body temperatures. Cod trypsins include trypsin I with an activity range of 4 to 65 °C (40 to 150 °F) and maximal activity at 55 °C (130 °F), as well as trypsin Y with a range of 2 to 30 °C (36 to 86 °F) and a maximal activity at 21 °C (70 °F). As a protein, trypsin has various molecular weights depending on the source.

Its habitat ranges from the shoreline down to the continental shelf. Several cod stocks collapsed in the 1990s (declined by >95% of maximum historical biomass) and have failed to recover even with the cessation of fishing. This absence of the apex predator has led to a trophic cascade in many areas. While the north west Atlantic cod stocks have not yet recovered fully from overfishing in the past, most stocks in the East Atlantic are currently in good condition and well managed, such as those at North Norway and Svalbard.

The direct selection for biological traits through fishery practices is the result of fishery management regulations, and gear restrictions and selectivities. The most obvious artificial selection for traits through management legislation can be observed in the imposed regulations on size, sex, seasonality, and locations. Catch size regulations vary with specificity to the targeted species and is often used to prevent exploitation during a specific part of the life cycle for the organism. Such regulations arose in response to the effects of FIE observed by the fisheries of Atlantic Cod (Gadus morhua).

Over 130 species from numerous classes of the animal kingdom call the bank home at least temporarily. Some such fish are the Atlantic cod, silver hake, yellow-tail flounder, blue-fin and yellow-fin tuna, striped bass, blue fish and numerous species of shark including the great white shark.Boston Globe, June 28, 2010 "Shark no reason to close beaches" Shellfish such as the American lobster, sea scallops, squid and ocean quahogs are also prevalent. Many marine birds call the bank home including gannets, shearwaters, storm petrels, fulmars, puffins and razorbills.

Shrimp fishery has the biggest economic importance as a part of fishery in the North Sea region because fishing common shrimps (Crangon crangon) is not limited by catch quota. On the other hand Atlantic cod, European plaice and common sole are hardly fished at all due to strict catch quota and other protection measures.Bericht der Landesregierung über die Situation und Entwicklung der Fischerei in Nord- und Ostsee sowie die Binnen- und Teichfischerei.

Georges Bank, while not having the most productive fishery in the world (the Grand Banks takes this claim), has great prominence in that it is probably the most geographically accessible of all the fishing banks in the North Atlantic. Lying adjacent to New England's famous seaports, Georges Bank is singlehandedly responsible for the development of coastal fisheries in towns such as Gloucester, Massachusetts, and Yarmouth, Nova Scotia. For over 400 years, Georges Bank supported lucrative fisheries for Atlantic cod and halibut. Over time, bottom trawlers became very efficient, some catching as much cod in an hour as traditional boats caught in a season.

Aega psora is a facultive parasite which temporarily attaches itself to its host and is able to survive independently. It probably spends the rest of the time resting on the seabed. It has been found as an external parasite on the Atlantic cod (Gadus morhua), the Greenland shark (Somniosus microcephalus), a shark in the genus Squalus, the common skate (Raja batis), the thorny skate (Amblyraja radiata) and the barndoor skate (Dipturus laevis). Large numbers have also been found in the stomach of a Greenland shark, though whether living as a parasite or as a commensal is unclear.

The leading plants of the shoreline are the large brown seaweeds, such as bladder, forked and knotted Wracks, and winged and sugar kelps, though there are also a number of red and green seaweeds present. Common animals of the seashore region include barnacles, tortoiseshell limpet, common periwinkle, blue mussels, sea anemones, sea slugs, sea urchins, starfish, and rock crabs. The deeper waters are home to a variety of fish, such as Atlantic cod, sculpins and cunners, halibut, haddock, sharks, and marine mammals, such as dolphins, porpoises, and whales. Whales seen off Newfoundland include Pilot whales, minkes, sei whales, fin whales and humpbacks.

This interaction may not always be negative. Studies have shown that certain invasive species have begun to shift cascades; and as a consequence, ecosystem degradation has been repaired. An example of a cascade in a complex, open- ocean ecosystem occurred in the northwest Atlantic during the 1980s and 1990s. The removal of Atlantic cod (Gadus morhua) and other ground fishes by sustained overfishing resulted in increases in the abundance of the prey species for these ground fishes, particularly smaller forage fishes and invertebrates such as the northern snow crab (Chionoecetes opilio) and northern shrimp (Pandalus borealis).

Several genes involved in mammalian nociception, such as brain-derived neurotrophic factor (BDNF) and the cannabinoid CB1 receptor are regulated in the fish brain after a nociceptive event. Somatosensory evoked potentials (SEPs) are weak electric responses in the CNS following stimulation of peripheral sensory nerves. These further indicate there is a pathway from the peripheral nociceptors to higher brain regions. In goldfish, rainbow trout, Atlantic salmon (Salmo salar) and Atlantic cod (Gadus morhua), it has been demonstrated that putatively non-noxious and noxious stimulation elicit SEPs in different brain regions, including the telencephalon which may mediate the co-ordination of pain information.

Lakes in central Massachusetts provide habitat for the common loon, while a significant population of long-tailed ducks winter off Nantucket. Small offshore islands and beaches are home to roseate terns and are important breeding areas for the locally threatened piping plover. Protected areas such as the Monomoy National Wildlife Refuge provide critical breeding habitat for shorebirds and a variety of marine wildlife including a large population of gray seals. Freshwater fish species in the commonwealth include bass, carp, catfish, and trout, while saltwater species such as Atlantic cod, haddock and American lobster populate offshore waters.

In November 2007, McDonald's lowered the use of New Zealand hoki and increased the use of Alaskan pollock, due to declining New Zealand hoki fishery sustainability and large cutbacks in the total allowable commercial catch of hoki by the New Zealand Ministry of Fisheries - from 250,000 tonnes in 1997 to 90,000 tonnes in 2007. McDonald's originally used Atlantic cod, before declining cod catches forced McDonald's to find sustainable fish elsewhere. McDonald's is trying to maintain fish only from areas certified as sustainable by the Marine Stewardship Council, but that is becoming more difficult each year. Hoki is still a major ingredient.

Close-up of the head, showing the strong teeth of this predatory species (upperside of fish on left, underside on right) Although primarily a bottom fish, it is often caught pelagically and it is thought to swim on its ventral edge rather than on the blind side. It is an active, midwater predator that feeds on prawns, fish (such as Atlantic cod, Artic cod, eelpouts, capelin, and redfish), and squid. It spawns at depths of during spring and summer, from April to July at temperatures of . Its eggs, larvae, and postlarvae are free-floating in deep water.

The North Sea cod stock is primarily fished by European Union member states and Norway. In 1999 the catch was divided among Denmark (31%), Scotland (25%), the rest of the United Kingdom (12%), the Netherlands (10%), Belgium, Germany and Norway (17%). In the 1970s, the annual catch rose to between 200,000 - 300,000 tons. Due to concerns about overfishing, catch quotas were repeatedly reduced in the 1980s and 1990s. In 2003, ICES stated that there is a high risk of stock collapse if current exploitation levels continue, and recommended a moratorium on catching Atlantic cod in the North Sea during 2004.

Upper Saddle River, NJ. It is possible to fish the stock down further to, say, 15% of the pre-harvest biomass, and then adjust the harvest rate so the biomass remains at that level. In this case, the fishery is sustainable, but is now overexploited, because the stock has been run down to the point where the sustainable yield is less than it could be. Fish stocks are said to "collapse" if their biomass declines by more than 95 percent of their maximum historical biomass. Atlantic cod stocks were severely overexploited in the 1970s and 1980s, leading to their abrupt collapse in 1992.

Cod is the common name for the demersal fish genus Gadus, belonging to the family Gadidae. Cod is also used as part of the common name for a number of other fish species, and one species that belongs to genus Gadus is commonly not called cod (Alaska pollock, Gadus chalcogrammus). The two most common species of cod are the Atlantic cod (Gadus morhua), which lives in the colder waters and deeper sea regions throughout the North Atlantic, and the Pacific cod (Gadus macrocephalus), found in both eastern and western regions of the northern Pacific. Gadus morhua was named by Linnaeus in 1758.

Spawning of northeastern Atlantic cod occurs between January and April (March and April are the peak months), at a depth of in specific spawning grounds at water temperatures between . Around the UK, the major spawning grounds are in the middle to southern North Sea, the start of the Bristol Channel (north of Newquay), the Irish Channel (both east and west of the Isle of Man), around Stornoway, and east of Helmsdale. Prespawning courtship involves fin displays and male grunting, which leads to pairing. The male inverts himself beneath the female, and the pair swim in circles while spawning.

However, some studies suggest that leading fish gain certain feeding benefits. One study of a migrating Atlantic cod shoal showed significant variability in feeding habits based on size and position in the shoal. Larger scouts consumed a more variable, higher quantity of food, while trailing fish had less variable diets and consumed less food. Fish distribution throughout the shoal seems to be dictated by fish size, and ultimately, the smaller lagging fish likely benefit from shoaling because they are more successful in feeding in the shoal than they would be if migrating individually, due to social facilitation.

Capture of Atlantic north-west cod in million tons In 1497 John Cabot became the first Western European since the Vikings to explore mainland North America and one of his major discoveries was the abundant resources of Atlantic cod off Newfoundland. Referred to as "Newfoundland Currency" this discovery yielded some 200 million tons of fish over five centuries. In the late 19th and early 20th centuries new fisheries started to exploit haddock, mackerel, and lobster. From the 1950s to the 1970s the introduction of European and Asian distant-water fleets in the area dramatically increased the fishing capacity and the number of exploited species.

The majority of these artificial environments found in Canada, are located in British Columbia, New Brunswick and as well as Newfoundland and Labrador. It takes about 6 months for the fish to hatch followed by a 2 to 3-year period for them to reach their maximize selling size, therefore taking an average of 3 years for a fish to reach market which is 3 to 5 kg. According to Fisheries and Oceans Canada (2014) in 2013 1 kg of Cod was being sold for on average $7.12 fish. Overall, Atlantic Cod are a relatively recent farmed fish, however are gaining popularity due to price, nutrition and feed to growth ratio.

Belugas occupy mostly the western side of the Cumberland Sound in spring and early autumn. In summer, they are found mainly in Clearwater Fiord and adjacent bays where they are reported to feed on a large diversity of fish and invertebrate species including squid, tube worms, caplin, Greenland cod and Atlantic cod. In late autumn and early winter, belugas move to the centre of the Sound, diving to depths of 300 m or more to feed on deep-water species such as Greenland halibut. Local hunters also report that belugas at the floe-edge in spring prey mainly on Arctic cod and turbot under the ice.

Fisheries-induced evolution is a function of the fishing-induced genetic drift, and to some extent represent the reduction of genetic diversity within the targeted population. For many exploited population, this reduction in genetic diversity has been predicted to reduce their adaptability to both environmental variability and ecological competitiveness. Indeed, the commonly observed fisheries-induced adaptation of younger and smaller size at sexual maturation counter specific life-history characteristics that would enable interspecies competition for resources. A biological model by Kindsvater and Palkovacs (2017) shows that FIE Atlantic cod, due to their smaller sizes, actually belong to a lower trophic level irrespective of their original position prior to the species moratorium.

The potential designation change (from Not At Risk to Endangered) was highly contentious, because many considered that the collapse of Atlantic Cod had resulted ultimately from mismanagement by DFO. The Report (section: Author's Recommendation of Status) therefore discussed at great length the process of developing a recommendation for the designation. The Report contained discussion addressing points that had been offered by DFO, because although COSEWIC had a mechanism for the 'jurisdiction' (i.e. the department responsible for the 'species' (here, for the population), to provide objections to an author), it had no mechanism for those objections to be objectively arbitrated as a matter of science.

The largest Norwegian food export (in fact the main Norwegian export of any kind for most of the country's history) in the past has been stockfish (tørrfisk in Norwegian). The Atlantic cod variety known as skrei because of its migrating habits, has been a source of wealth for millennia, fished annually in what is known as the Lofotfiske named for the island chain of Lofoten. Stockfish has been a staple food internationally for centuries, in particular on the Iberian peninsula and the African coast. Both during the age of sail and in the industrial age, stockfish played a part in world history as an enabling food for cross-Atlantic trade and the slave trade triangle.

The same Norwegian study coincided that another eagle when trying to fly with an Atlantic cod (Gadus morhua) weighing about , the fish was quickly dropped as it was apparently deemed too heavy. The widely reported case of a white-tailed eagle carrying off a 3.5-year-old girl in Norway flight by the back of her dress only to drop her mostly unharmed below the eagle's eyrie, which was included in the Guinness Book of World Records, is considered most likely to be apocryphal since she weighed approximately , far too heavy for any living eagle to lift in flight.

The distinction between demersal species of fish and pelagic species is not always clear cut. The Atlantic cod (Gadus morhua) is a typical demersal fish, but can also be found in the open water column, and the Atlantic herring (Clupea harengus) is predominantly a pelagic species but forms large aggregations near the seabed when it spawns on banks of gravel. Two types of fish inhabit the demersal zone: those that are heavier than water and rest on the seabed, and those that have neutral buoyancy and remain just above the substrate. In many species of fish, neutral buoyancy is maintained by a gas-filled swim bladder which can be expanded or contracted as the circumstances require.

Gadus morhua (Atlantic cod) range map Cod populations or stocks can differ significantly both in appearance and biology. For instance, the cod stocks of the Baltic Sea are adapted to low-salinity water. Organisations such as the Northwest Atlantic Fishery Organization (NAFO) and ICES divide the cod into management units or stocks; however these units are not always biologically distinguishable stocks. Some major stocks/management units on the Canadian/US shelf are the Southern Labrador-Eastern Newfoundland stock (NAFO divisions 2J3KL), the Northern Gulf of St. Lawrence stock (NAFO divisions 3Pn4RS), the Northern Scotian Shelf stock (NAFO divisions 4VsW), which all lie in Canadian waters, and the Georges Bank and Gulf of Maine stocks in United States waters.

Prior to the fishing technological revolution that has led to the species moratorium, the exploitation of Atlantic Cod have been selective towards larger-sized fish since the 1500s. Catch data for the species have quantitatively shown that this selectivity for larger fish for over 500 years have shifted the life-history patterns, resulting in earlier sexual maturation and smaller sizes at said maturation. Sexual selectivity by a fishery works on the theoretical foundation that the preservation of females allows their reproductive input to offset the fishing mortality. Fisheries of species with low fecundity such as mud crabs (Scylla serrata) and blue swimmer crabs (Portunus armatus) often adopt this method and only allow the harvesting of males.

Farming of Atlantic cod has received a significant amount of interest due to the overall trend of increasing cod prices alongside reduced wild catches.The State of World Fisheries and Aquaculture 2010. fao.org. . However, progress in creating large scale farming of cod has been slow, mainly due to bottlenecks in the larval production stage, where survival and growth are often unpredictable. It has been suggested that this bottleneck may be overcome by ensuring cod larvae are fed diets with similar nutritional content as the copepods they feed on in the wild Recent examples have shown that increasing dietary levels of minerals such as selenium, iodine and zinc may improve survival and/or biomarkers for health in aquaculture reared cod larvae.

The coastal waters of the remote Lofoten islands are one of the richest fishing areas in Europe, as most of the Atlantic cod swims to the coastal waters of Lofoten in the winter to spawn. So in the 19th century, dried cod was one of Norway's main exports and by far the most important industry in northern Norway. Strong sea currents, maelstroms, and especially frequent storms made fishing a dangerous occupation: several hundred men died on the "Fatal Monday" in March 1821, 300 of them from a single parish, and about a hundred boats with their crews were lost within a short time in April 1875.Tim Denis Smith Scaling Fisheries: The Science of Measuring the Effects of Fishing, 1855–1955, Cambridge University Press, 1994 , pp.

Aquatic animals such as Greenland shark, wolf fish, Atlantic cod, Atlantic halibut and Arctic char must cope with the sub-zero temperatures in their waters. Some aquatic mammals, such as walrus, seal, sea lion, narwhals, beluga whales and killer whales, can store fat called blubber that they use to help keep warm in the icy waters. Some ungulates that live in frigid conditions often have pads under their hooves to help have a stronger tension on the icy ground or to help in climbing up on rocky terrain. But mammals that already have a pad under their foot such as polar bears, wolverines, Arctic wolves and Arctic foxes will have fur under their pads to help keep their flesh concealed from the cold.

Atlantic cod stocks were severely overfished in the 1970s and 1980s, leading to their abrupt collapse in 1992 According to a 2008 UN report, the world's fishing fleets are losing US$50 billion each year due to depleted stocks and poor fisheries management. The report, produced jointly by the World Bank and the UN Food and Agriculture Organization (FAO), asserts that half the world's fishing fleet could be scrapped with no change in catch. In addition, the biomass of global fish stocks have been allowed to run down to the point where it is no longer possible to catch the amount of fish that could be caught. Increased incidence of schistosomiasis in Africa has been linked to declines of fish species that eat the snails carrying the disease- causing parasites.

Noxiously stimulated common carp show anomalous rocking behaviour and rub their lips against the tank walls Noxiously stimulated zebrafish reduce their frequency of swimming and increase their ventilation rate Noxiously stimulated Atlantic cod display increased hovering close to the bottom of the tank and reduced use of shelter Studies show that fish exhibit protective behavioural responses to putatively painful stimuli. When acetic acid or bee venom is injected into the lips of rainbow trout, they exhibit an anomalous side-to-side rocking behaviour on their pectoral fins, rub their lips along the sides and floors of the tanks and increase their ventilation rate. When acetic acid is injected into the lips of zebrafish, they respond by decreasing their activity. The magnitude of this behavioural response depends on the concentration of the acetic acid.

Thiamine deficiency in eggs results from an unbalanced diet abundant in fatty prey fish, such as young sprat, from which the supply of thiamine is insufficient in proportion to the supply of energy and unsaturated fatty acids for salmon. Relationships between fish stock changes in the Baltic Sea and the M74 syndrome: The M74 syndrome is connected to a weak Atlantic cod (Gadus morhua) stock and strong year classes of sprat in the Baltic Sea. Since the collapse, heavy fishing mortality as well as predation on cod eggs by sprat and food competition between sprat and young-of-the-year cod has inhibited cod recovery. Coincidentally with the decline in the cod stock since 1982, and following the consequent reduction in predation pressure, the sprat stock increased rapidly, and salmon therefore had more food.

Michael Harris Live on CFRA Ottawa was cancelled February 9, 2012. He is now a columnist for the website iPolitics. His book 1986 book Justice Denied: The Law Versus Donald Marshall detailed the story of Donald Marshall, Jr.’s wrongful conviction in 1972. His investigative journalism culminating in the book Unholy Orders: Tragedy at Mount Cashel, triggered the Hughes Inquiry into the allegations of abuse at the Mount Cashel Orphanage. Harris also authored Rare Ambition: The Crosbies of Newfoundland, Con Game: The Truth About Canada’s Prisons and the national best seller Lament for an Ocean: The Collapse of the Atlantic Cod Fishery. Elizabeth May, the executive director of the Sierra Club of Canada called it "The definitive book on the cod catastrophe... After reading this book, you wouldn’t trust the Department of Fisheries and Oceans with your aquarium" (cited on back jacket cover).

In 2014, the U.S. Food and Drug Administration revealed that the official scientific name for the fish was changed from Theragra chalcogramma back to its original taxon Gadus chalcogrammus, highlighting its close genetic relationship to the other species of the cod genus Gadus. Alaska pollock was long put in its own genus, Theragra, and classified as Theragra chalcogramma, but more recent research has shown it is rather closely related to the Atlantic cod and should therefore be moved back to Gadus, where it was originally placed. The change of the official scientific name was followed by a discussion to change the common name as well, to highlight the fish as a member of the cod genus. The common names "Alaska pollock" and "walleye pollock", both used as trade names internationally, are considered misleading by scientific and trade experts, as the names do not reflect the scientific classification.

The key tactics used to avert any at-risk listing centered on the issue of stock discreteness, and DFO's single-stock stance within COSEWIC contradicted the multiple-stock hypothesis supported by the most recent science (including DFO's, hence DFO's earlier and proper demand that the report address these). Bell has argued that this contradiction between fact and tactic effectively painted management into a corner from which it could not acknowledge or explain the contrast between areas where conservation measures were clearly needed and areas where opposite observations were gaining press attention.Endangered Cod, Red Herrings, Harps, and Hamster Wheels In effect, DFO's opposition to a listing compromised its ability to carry out its conservation mandate. In 1998, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) listed the Atlantic cod as "vulnerable", a category subsequently rebranded as "special concern", though not as an endangered species.

Upogebia deltaura, a mud lobster commonly found in Scottish maerl beds Further action on a much wider scale may be required. According to a recent report "Scotland's marine life could be almost wiped out within 50 years unless tough action is taken to manage the way humans use the seas". Fears were expressed by a consortium of environmental organisations that commercial fish stocks, including Atlantic cod are suffering from over-fishing, that fish farming, especially for salmon is damaging the aquatic environment, a reduction in coastal marsh habitats is affecting marine bird life, litter in densely populated estuaries such as the Firth of Clyde is affecting all forms of marine life and that the growth in off-shore tourism was deleterious to populations of, for example, basking shark. A call was made for a 'Scottish Marine Bill' to co-ordinate and manage human activity at sea and to provide more protected areas such as marine national parks.

They were found to feed almost exclusively on Atlantic mackerel in the northern North Sea, while the same was true for sandeel in the eastern North Sea. Off Iceland, they mainly fed on sandeel (nearly 58 per cent of sampled individuals), haddock (22.6%), herring (20%), capelin (19.4%), and Atlantic cod (14.7%), with the rest of the diet consisting of euphausiids, various larger species of gadiods, and Norway pout. Sandeel was more important in southern Iceland (constituting 78 per cent of sampled individuals), while capelin (35.1%), haddock (28.7%), and cod (22.3%) were more important in the north. Euphausiids were only consumed in the north. Although haddock was only a minor part of the diet the first couple years of the study (0 and 4% in 2003 and 2004, respectively), it subsequently constituted a major component of it (31-35% in 2005–2007), while sandeel's importance in the south declined considerably (95.2 to 77.7% from 2003–2006, but only 18.1% in 2007).
